After more than one hundred years from the date of its birth, Einstein gravity
remains to be the most promising theory of relativistic gravity.
However, there are several reasons to look at alternative theories of gravity,
for instance, the need for a renormalizable quantum theory of gravity, the interpretation
of the expanding universe and the galaxy rotation curves, etc.
Among the numerous choices of extended theories of gravity, conformal gravity
has attracted considerable interests, partly because of its on-shell equivalence to
Einstein gravity and its power counting renormalizability [1]},
and partly because of the fact that its spherically symmetric solution
contains a term linear in radial coordinate which may play some role in
explaining the galaxy rotation curves
as an alternative for dark matter [2]}, [3]}.
As a physically viable model of relativistic gravitation,
it is natural to look into more detailed behaviors of conformal gravity,
and the study of its black hole solutions and
the corresponding thermodynamic properties [4]}, [5]}, [6]}
is of great importance in this regard.
